Specification of Letters Patent.

Application filed April 29, 1904. Serial No. 205354.

T 0 all whom it may concern:

Be it known that I, THOMAS CnnIs'rMAs EDWARDS, a subject of the King ofGreat Britain, residing in London, England, have invented certain newand useful Improvements in Cornets or the Like, of which the followingis a specification.

This invention is primarilydesigned for the purpose of rectifying errorsin wind musical instruments, such as cornets and the like, which havevarious additional lengths of tubing brought into operation by means ofpistons or valves in order to produce various tones. In such instrumentsthe normal (or shortest) length of tubing communicates with all thepistons or valves, which latter are adapted to connect said length oftubing with one or more loop tubes of varying lengths and these, whenthe pistons are depressed, consequently become added to the normal tubeand so increase its length. Ordinarily these loop tubes are of imperfectlength for two or more of them to be used in conjunction, being tooshort When. two or more are brought simultaneously into operation toproduce sounds of correct pitch.

This invention aims to obviate the above defects and to provide aninstrument which has a comparatively great range of tone and in whichthe tones are of the correct pitch.

ith this end in view, the invention con sists in a wind musicalinstrument which.

embodies the novel features, arrangements and combinations of parts tobe hereinafter described and claimed In the accompanying drawings, inwhich the same reference characters denote the same or correspondingparts throughout the several views, Figure l is a side-elevation of aninstrument constructed in accordance with the invention, showing thelower loop tubes, Fig. 2 is a view in elevation of the opposite side ofthe instrument, showing the upper loop tubes, Fig. 3 is a plan of Fig.2, Fig. 4 is an enlarged vertical sectional view on line 4, 4, Fig. 3,Figs. 5 to 12 are similar sectional views, showing diagrammatically thedifferent passages and their connection in order to produce tones ofdifferent pitch, and Figs. 5 to 12 are horizontal cross-sec tionscorresponding respectively to Figs. 5 to 12, as hereinafter explained.

Referring to the drawings, (t denotes the inlet to the main tube of theinstrument, which inlet leads to the third. valve or piston B, thecasing B of which it enters at (L In the normal position of the pistons,as shown 1n Figs. 1, 2, 4 and 5, the air is led from the tube a throughthe casing B and port I) in the piston-valve B, connecting passage yport 0 in the second piston-valve C, connecting passage y port (1 in thefirst piston-valve D, and thence into the return-loop a, through whichit is led back to the port f in the piston B and emerges from thepiston-valve B into the main tube g. The air is conducted through thecontinuation of this tube y to the bell 7t.

Fig. 5 and Fig. 5 show in diagrammatic form the normal air-passagethrough the instrument, this position of the valves being known as thefirst position. If now the second piston C be depressed, i. e. in thesecond position as shown in diagrammatic form in. Figs. 6 and 6 the port0 is moved down and disconnected and the port i in the piston Cconnected. with the port I), thus leading into the shortest lower looptube F (Fig. 1) from which latter the passage is continued throughtheport in the piston C, through the port d and returnloop c as before,to the main tubing 9 and thence to the bell h; the said ordinary loop Fto lower the pitch one semitone being thus put in connection, as usual.If new the first piston D alone be depressed, i. e. in the ,thirdposition, as shown in Fig. 7 and Fig. 7, thereby the port at will bemoved down and disconnected and the port 76 is moved down opposite thepassage y from the port 0. This causes the air to be led. through theconnecting passage and lower loop-tube G from which the air is ledthrough the port Z into the return-loop e and then into the main tube 9and bell 72, as before, thus adding the second loop G to the main tubingto lower the pitch two semitones as usual.

When the third piston B alone is depressed, i. c. in the fourthposition, as shown in diagrammatic form in Fig. 8 and Fig. 8, the portI) in said piston B will be moved down and disconnected and thereby thelower air-passage through the ports I), c and d and return-loop c isentirely out offthe air-passage from the tube a to the piston B nowleadsthrough the port m in said piston B and thence through the connectingtube a; the port i in the piston C and the short bend. a to the port Zin the piston D which leads into the longest loop tube H. This lattertube terminates in the valve-casing B at a point opposite the openingthrough the valvecasing B leading into the main tube g. Said tube H andthe main tube 9 are now put in connection through the port it in thepiston B when the latter is depressed. Thus the length of the loop tubeH is added to the main tubing by the depression of the valve B, thisadditional tube H being made of sufficient length to correctly lower thepitch three semitones below that of the normal tube.

In the fifth position, with the pistons B and C both depressed together,as shown in Fig. 9 and Fig. 9, the air in the tube (1V is led,

by means of the upper air-passage at, through the port m in the piston Binto the port 0 in the piston C, which port 0 in the piston C leads at Yinto the shorter upper loop tubing Y (i. e. the smaller additional looptube) the termination Y of which loop tube Y communicates through theport p in the piston C and the connecting tube 0: with the port Z andloop tube H and port it through which the air is led to the main tube 9.The length of both the loop tube H and loop tube Y (which is of somewhatgreater length than the loop tube F) is thus added to the main tube soas to correctly lower the pitch four semitones below that of the normaltube.

In the next position, i. e. the sixth position, with the pistons B and Ddepressed together, as shown in diagrammatic iorm in Fig. 10 and Fig. 10the passage is made from the tube (1 through the port m in the piston B,and connecting tube a: thence through the port i in the piston C (whichlatter is not depressed) and the connecting tube 90 to the port r in thepiston D. The port 7", with the piston D in this depressed position,communicates at Z with the up er loop tube Z, which latter at its end Zleac s the air through the port 8 in the now-depressed piston D directlyinto the loop tube H, and thence through the port at to the main tube 9and bell h, thus adding to the main tube the length of both the looptube H and the additional loop tube Z. The latter is of somewhat greaterlength than the loop tube Gr so as to correctly lower the pitch fivesemitones below that of the normal tube.

In the next position, that is, in the seventh position, where all threepistons are depressed, as shown in Fig. 11 and Fig. 11, the passage ismade from the tube a through the port m in the piston B, connecting tubea: the port 0 in the piston C, and upper loop tube Y, back to the port19 in the piston C, and thence through connecting tube :0 to the port1", through the upper loop tube Z back to the port 8 in the piston D andthence to the loop tube H, through the port it in the piston B to themain tube 9 and bell it, thus adding all three loops Y, G and H to thenormal tube to thereby correctly lower the pitch siX semitones.

Fig. 12 and Fig. 12 show diagrammatically the first and second pistonsdepressed, while the third piston is in normal position, thusrepresenting an alternative fourth position, in which case the passageis through the tube a, lower the port Z) in the third piston B, andconnecting tube y thence through the port 2' and lower loop tube F backto the port j, thence through the connecting tube 3 and the ort 7c inthe valve D round the lower loop tu e G, back to the return-loop e,through which it leads to the port f in the piston B and emerges fromthe piston B into the main tube g, and thence through the continuationof this tube g to the bell h.

For tuning in the first position, the part g of the main tube g may bearranged as a slide for tuning purposes, as usual; or if desired thereturn-tube 6 may be provided with or formed as a slide for the purposeof such tuning.

If desired an extra valve or valves may be provided for still furtherlowering the pitch of the instrument in any known or suitable manner,such additional valve or valves being arranged in suchwise or in suchparts of the main tubing as not to interfere with the valve system and uper and lower loo tubes, etc., as herein efore described wit respect toand as illustrated in the drawings.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:
